My 1 yr old shower built by the contractor started leaking like a sieve. In my efforts to remedy the problem, I ended up demolishing the whole thing to the stud while throwing out moldy drywall and replacing moldy stud base plates.
He used a Kerdi shower base, but didn't apply any waterproofing to the sidewalls. I managed to save the Kerdi drain flange. It's in pretty good shape (see picture). Can I build a new Kerdi shower pan using the old flange, or should I get a new one?
Schluter will not recommend reusing an already used shower drain. I would never reuse the same drain myself in my shower repairs. Although, BUILDERS reuse them all the time, to save a buck or two. But my guess is you really want to reuse it, no one can stop you from doing that. A few tips to consider: looks like you have a large flange ABS Kerdi shower drain. If the fleece fabric is intact technically it is still good. Make sure it is clean and run a water test to make sure it does not leak. Bond the new polyethylene membrane using Schluter Kerdi Coll - L only as well as the prefabricated corners and seals along the tray and curb if there is one.
